Star Wars has a long history of using repurposed items as props. The best example of this is the original lightsaber, which was just a Graflex flashgun, essentially a camera's flashbulb.
Other props were borrowed from other shows and movies, in the case of bounty hunter Bossk's flight suit in The Empire Strikes Back, that costume is from a Doctor Who episode. And countless other props which found their way to a Galaxy Far, Far Away thanks to the scrappy ingenuity of the prop masters on set and behind the camera.
